Each cousin will get 0.75 cents because you would have to divide $2.25 by 3. I hope this helps.
Solve for f:(i - 47/12) + f = 18
(i - 47/12) + f = f + (-47/12 + i):
f + (-47/12 + i) = 18
Subtract -47/12 + i from both sides:
Answer: f = 263/12 - i
Subtract 43 from both sides
-6p=-30
Divide both sides by -6
p=5
Final answer: p=5
